FEED-TABLE FOR ROLLING-MILLS.

SPECIFICATION forming part of Letters Patent No. 572,17 5, datedDecember 1, 1896.

Application filetl March 23, 1896. Serial No. 584,404. (No model.)

To aZZ whom it may concern:

Be it known that I, WILLIAM H. McFAD- DEN, a cit-izenof the UnitedStates, residing at Allegheny, in the county of Allegheny and State ofPennsylvania, have invented or discovered a certain new and usefulImprovement in Feed-Tables for Rolling-Mills, of which improvement thefollowing is a specification.

The invention described herein relates to certain improvements in millsfor rolling sheet metal, and has for its object a feed-table whereby thesheets maybe automatically fed from one set of rolls to an adjacent setof rolls, thereby rendering it possible to employ a continuous form ofmill for the production of sheet metal.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification,Figure 1 is a sec-. tional plan view of a sheet-mill embodying myimprovement. Fig. 2 is a side elevation of the same. Fig. 3 is atransverse section of the feed-table, the plane of section beingindicated by the line III III, Fig. 2; and Fig. 4: is a transversesection of the feed-table, illustrating a modification in the mountingand driving of the feed-rollers.

In the practice of my invention the mill consists of two or more standsof rolls A B, &c., arranged in line with and in suitable proximity toeach other. Between the stands of rolls is arranged a feed-table adaptedto receive a sheet from one pair of rolls and deliver it to the nextpair. It is preferred to support the side bars 1 of the table on lugs 2on the housings of the rolls. The side bars are provided with bearingsfor the lower or positively-driven rollers 3 and with bearings for theupper or frictionally-drivenrolls at, the bearings for the two seriesbeing arranged in or approximately in line one above the other, as shownin Fig. 2. The lower rolls may be driven in any suitable manner, butpreferably by means of a chain or belt 5, passing around the journal ofone of the rolls or a sprocket-wheel 6 thereon and 2. correspondingwheel on the extended journal 7 of one of the lower rollers, as clearlyshown. Movement is transmitted from one roller to the next by a chain orbelt 8. The table is arranged at such a height on the housing that aplane tangential to the rolls at their point of contact will betangential orapproximately so to both sets or series of feed-rollers attheir points of contact, (shown in Fig. 2,) so that a sheet passingfrom'between rolls will be fed between the feed and be by them fed intothe next pair of rolls. As the sheets vary in thickness, the bearingsfor the upper rolls are elongated, as shown in Fig. 2, to permit theupper rollers to rise as the sheet comes between the two series ofrollers, so that the sheets are pressed against the positively-drivenfeedrollers by a force equal to the weight of the addition to increasingthe effectiveness of the feeding action the upper rollers will preventthe sheets from bending or twisting while passing between the two standsof rolls, thus insuring their proper delivery to succeeding rolls.

- In order to prevent the drooping of the ends of sheets between thepairs of rollers, a supporting-plate 9 is arrangedbetween adjacent pairsof feed-rollers. These plates are provided at their ends with angularextensions lQ yhich rest upon the side bars 1 and support the plate 9 inor approximately in a horizontal plane tangential to the top of thelower roller. I

As shownin Fig. 4, the journals of both series of rollers may be mountedin slots in the side bars 1 and the journals of the lower rollerssupported on springs 11. In this construction the lower rollers wouldmove down from the upper rollers as sheets were fed between them. Ifdesired, the upper rollers may be positively driven and the lowerrollers driven by frictional contact with the sheets or upper rollers,as shown in Fig. 4.

I claim herein as my invention- 1. The combination in a feed-table forrollin g-mills of two series of feed-rollers, the rollers of one seriesbeing arranged to press the sheets against the rollers of the otherseries, and means for positively driving the rollers of one series,substantially as set forth.

2. The combination, in a feed-table for rolling-mills, of a series ofpositively-driven rollers, a series of supporting-plates intermediate ofthe rollers, and a series of rollers arranged to press the article beingfed against the posi- I 5 tively driven rollers, substantially as setforth.

In testimony whereof I have hereunto set my hand.
